The vulnerability allows an adjacent attacker to execute arbitrary code on the target system.

The vulnerability exists due to improper security restrictions and insufficient validation of user-supplied input. An adjacent attacker with access to a Spark standalone cluster can send a specially crafted request that submits malicious input and execute arbitrary code on the master host, which could be used to conduct further attacks.
